Abstract

In this study, the photolytic decoloration of carmine (C.I. Natural Red 4) via UV radiation in the presence of H₂O₂ was optimized using response surface methodology (RSM). According to analysis of variance (ANOVA) results, the proposed model can be used to navigate the design space. It was found that the response of carmine degradation is very sensitive to the independent factors of carmine concentration, H₂O₂ concentration, pH and reaction time. The proposed model for D-optimal design fitted very well with the experimental data with R² and R_adj² correlation coefficients of 0.998 and 0.997, respectively.
